How to search a string for multiple values and replace with another string

Cookies are unable to be generated when having HttpOnly.

this is mine.

      set cookiename [getfield $cookievalue "=" 1]
      set namevalue ""

            }
            append newcookievalue "; $elementname=$elementvalue"
          } else {
            append newcookievalue "; $element"
          }
        }
      }
      set cookielist($cookiename) "$namevalue$newcookievalue"
    }
    HTTP::header remove "Set-Cookie"
    foreach cookiename [array names cookielist] {
      log local0. "Remove CookieName = $cookielist($cookiename) ProxyPass"
      HTTP::header insert "Set-Cookie" $cookielist($cookiename)
      log local0. "Inserting cookie: $cookielist($cookiename)"
    }
  }
}
}

I wanted to string the string "HttpOnly" or "httponly" out of the cookie line.

anyway, if you want, you may use string map to remove httponly (i.e. replace it with null).

set cookievalue [string map -nocase {"httponly" ""} $cookievalue]
